A laboratory two‐roll mill technique and chemical analysis procedures were used to determine the source of plate‐out problems associated with plasticized, barium‐cadmium‐zinc stabilized, poly(vinyl chloride) extrusion wire coating compounds. The results of this study indicated that the barium‐cadmium‐zinc heat stabilizer was the main contributor to the plate‐out problem. It was further shown that the plasticizer participated in the plate‐out process while a secondary heat stabilizer system did not. Using the two‐roll mill technique, it was possible to optimize the poly(vinyl chloride) compound to minimize plate‐out while maintaining optimum physical properties.
